ASSIGNOR OF ONE-HALF TO WM. GORDON CRAWFORD, OF WASHINGTON, DISTRICT OF COLUMBIA.

SHUTTER-WORKER.

Specification of Letters Patent.

Patented Aug. 14, 1906.

To all whom it may concern:

Be it known that I, JAMES LEE SIMMoNs,of Washington, District of Columbia, have in vented certain new and useful Improvements in Shutter-Workers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is to enable the operating-rods of shutter-workers to be extended at different angles through window-frames.

A further object is to utilize the weight of a shutter to insure the cooperating parts be ing always in engagement.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view with parts broken away, the shutter being indicated in its closed position in full lines and in its opened position in dotted lines. Fig. 2 is a sectional view on line 2 2, Fig. 3. Fig. 3 is a sectional view on line 3 3, Fig. 1. Fig. 4 is a detail.

Referring to the drawings, 1 designates a housing, having right-angular walls 2 and 3 designed to fit against the side of a windowframe, the wall 2 being against the outer face thereof, while the wall 3 is against the side face. The wall 2 is formed with an elongated opening 4, through which is passed the operating-rod 5. This opening is sufficiently wide to permit the rod to extend therethrough, either on a straight line, as indicated in dotted lines in Fig. 1, or at actute angles, as shown in full lines in Figs. 1 and 2. This enables the rod to be passed through a solid portion of the window-frame or the building-wall and to accommodate itself to different conditions. If the rod had to be passed on a straight line, the frame might not afford sufiicient bearing therefor, and then, too, it might interfere with the window-sash 6 designates a toothed wheel, having an axial spindle 7 projecting downwardly therefrom and a circumferential flange 8, which overhangs a flange 9, surrounding an opening in the top of easing 1, such flanges serving to prevent rain or snow from entering the housing. This wheel carries plates 10,

ter 12, and thus forms one of the hinges. The depending teeth of wheel 6 are slightly beveled and intermesh With a worm 13, from which projects rod 5. This worm rests in bearings 14., extending laterally from a casting 15, having a slightly elliptical opening to accommodate spindle 7. Concentric to this spindle the casting 15 has a depending flange 16, which extends into an opening in the bottom of housing 1, so that the casting may be turned axially concentrical with wheel 6( It is in this way the rod 5 may be extended outwardly from the housing at different angles, as before stated. By making the opening in casting 15 slightly elli tical and by beveling the teeth of wheel 6 t e tendency is to force spindle 7 toward the far side of the opening, thus avoiding any shaking of the shutter. To limit the axial movement of the casting 15, screws or stop-lugs 17' depending therefrom are extended through curved slots 18 in the bottom of the housing.

From what has been said it will be seen that the weight of the shutter will always tend to hold; the toothed wheel 6 in engagement with the worm of the operating-rod, and that therefore it is only necessary to turn this rod axially to effect the partial revolution of wheel 6, and hence the working of the shutter.

The advantages of my invention will-be apparent to those skilled in the art. It will be seen that by means thereof the housing for the operating parts may be'secured to the right-angular faces of a window-frame and yet allow the operating-rod to be passed through a solid portion of the frame or wall of the building. No matter what angularity is assumed by the rod the operating-wheel will always remain in mesh with the worm. A shutter-worker constructed in accordance with my invention is extremely simple and inexpensive and not liable to'readily get out of order.

I claim as my invention 1. A shutter-worker comprising a casing having an elongated opening in one wall, a wheel designed to be secured to a shutter and fitted within said casing, a worm meshing with said wheel, a bearing for such worm movable concentrically with respect to the which are designed to be secured to a shutaxis of said wheel, and an operating-rod eitending from said worm through said openmg.

2. A shutter-worker comprising a casing having right-angular walls one of which is formed with an elongated opening, the top of said casing having a circular opening, a wheel fitted in said latter opening having teeth on its under side, a worm meshing with said teeth, a bearing for said worm mounted concentrically with respect to said wheel, and a rod" extending from said worm through the opening in the casing-wall.

3. A shutter-worker comprising a casing having an opening in its top and a surrounding flange, a wheel dependin through said opening and having a circum erential flange overlapping the first-mentioned flange, a worm in mesh with said wheel, and an operating-rod secured to said worm.

4. A shutter-worker comprising a casing, a wheel fitted within said casing and having a central spindle and beveled teeth on its under side, a worm meshing with said teeth, a

bearing for said worm movable concentrically with respect to said wheel and having an elliptical opening to accommodate said spindle.

5. A shutter-worker comprising a casing having right-angular walls one of which is formed with an elongated opening, the top of such casing having a circular opening, a wheel fitted in said circular opening and toothed on its lower face, a spindle depending from said wheel, a worm meshing with said wheel, a bearing for said worm having an opening to accommodate such spindle, said bearing being journaled in the bottom of such casing, and an operating-rod secured to said worm and extended through the opening of the side wall of the casing.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JAMES LEE SIMMONS.
